# kill_dependency

From cppreference.com
< c‎ | atomic

Defined in header ``<stdatomic.h>`` |  |
A kill_dependency( A y ); |  | (since C11)

Informs the compiler that the dependency tree started by an memory_order_consume atomic load operation does not extend past the return value of `kill_dependency`; that is, the argument does not carry a dependency into the return value.

The function is implemented as a macro. `A` is the type of y.

### Parameters

y | - | the expression whose return value is to be removed from a dependency tree

### Return value

Returns y, no longer a part of a dependency tree.
